The Legend of Zelda: The Wind Waker - Yellow ChuChu

Yellow ChuChus are one of a species of ChuChus that Link encounters in the game. They have electricity running through its body, meaning that Link will get hurt if he strikes it with his sword. Link needs to stun it with the Boomerang first, then strike with the sword, or just shoot it with arrows. Yellow ChuChus will drop either a Red Chu Jelly or a Green Chu Jelly when it is killed.
